Over the course of Day 9, Jack traveled through London in his efforts to thwart the terrorist attack which was planned by Margot Al-Harazi in revenge for the death of her husband in a drone strike three years before. Margot planned to destroy several key locations in London if President Heller didn't surrender himself to her for execution. Jack, with the help of Chloe, CIA agent Kate Morgan and Open Cell managed to obtain proof of the terrorist attack and get Heller to ground the drone fleet, but not before Margot gained control of six of the ten drones she'd planned on. Margot broadcast a threat message demanding the surrender of Heller in three hours or thousands of lives in London would be lost. Jack's efforts led him to Simone Al-Harazi who ended up in St. Edwards Hospital after chasing her niece and getting hit by a bus. To stop Simone from talking, Margot bombed the hospital with a drone strike, apparently killing a lot of people and injuring even more, but Jack managed to evacuate the hospital due to realizing the strike was coming in time to save many lives. When the deadline approached and there was no real progress on finding Margot, Heller decided to surrender himself in exchange for Margot destroying the drones. She agreed and with Jack's help, Heller stood in the middle of Wembley Stadium to be killed by a drone strike. Using information Simone led them to that her husband Naveed had left, Jack was able to save Heller with Chloe's help and then trace Margot who destroyed five of the six drones before seeing through the deception. She targeted Waterloo Station in revenge, but Jack and Chloe managed to track her with the help of Adrian Cross in time to redirect the missile into the Thames River. Margot was killed and the threat to London ended.
